EDEN PRAIRIE, Minn. -- Emmanuel Arceneaux is going to get his chance with the Minnesota Vikings after all.

An NFL source said on Monday afternoon the Vikings have signed Arceneaux off the practice squad to a three-year deal.

"He's been such a hard worker in practice and really has a good feel for what we're trying to do onoffense," coach Leslie Frazier said, a couple of hours before the Vikings confirmed the move in a media release.

"We don't feel like we'll have any issues with him understanding our offense and what's expected of him, and his work ethic has been so good. We think he'll be a plus for us. He's an excellent blocker, has good hands, has pretty decent speed. But his work ethic is one thing we'll really appreciate once we get him up on the 53."

He replaces rookie Stephen Burton, who suffered damage to the medial collateral ligament in one of his knees in Sunday's loss at Detroit and was placed on injured reserve.

Arceneaux, 24, signed a three-year deal with the Vikings in January that included a $75,000 signing bonus. He starred in the Canadian Football League the previous two years but struggled to adjust to the NFL game in training camp.

"That was part of it -- him just making the adjustment to the way football is played here compared to where he had come from and the things we asked him to do," Frazier said. "We ask our receivers to block a lot because of our run game and what we do with Adrian (Peterson). But that was a part of it. Just adjusting from that style of football, which is so wide open in the CFL. But he's made that adjustment and looking forward to seeing how he performs."

The Vikings passed over Arceneaux twice already this season, signing Burton off the practice squad and re-signing Burton again after a season-ending injury to Michael Jenkins.
